Main functions and characteristics
SF6 decomposition detector can quickly detect and judge the early faults inside SF6 electrical equipment (circuit breaker, transformer, TRANSFORMER, GIS and bushing, etc.) in the field by simultaneously monitoring SO2 and H2S decomposition products.
This instrument can be widely used in SF6 electrical equipment in electric power, railway, metallurgical and petrochemical industries.
SF6 electrical equipment internal gas by the pressure reducing valve, airway after entering instruments, two road into the SO2 and H2S sensor for testing at the same time, the SO2 and H2S concentration into corresponding electrical signal, through the operational amplifier, filter circuit, sent to the microprocessor and A/D converter, the analog signal is converted into the corresponding digital signals, the LCD display detection concentration of actual value.The memory number can be compared by the microprocessor logic with the expert diagnosis system to determine the type of fault.
